Description
Technical field
The present invention relates to aircraft airborne function mounting unit strength test field, is overloaded more particularly to a kind of wall panel structure
Testing equipment.
Background technology
Installation multiple equipment is generally required on aircraft airborne function mounting unit (wall panel structure), is generally required to multi-functional
Installation unit carries out intensity examination, and intensity applies it when examining overload of the installed equipment under different flight state and carries
Lotus.
When the size and smaller weight of airborne equipment and airborne equipment installation unit, can be simulated using centrifugal testing machine
Carry, this test method is closer to truth.But when airborne equipment and airborne equipment installation unit size and weight compared with
When big, general centrifugal testing machine just can not often meet test requirements document, design new centrifugal test device to realize overload examination
Higher design and manufacture cost will often be spent by testing, and considerably increase experimentation cost.
Therefore, when large-sized airborne equipment and airborne equipment installation unit carry out overload test, can be added using static(al)
The mode of load realizes overloading load.But often airborne equipment quantity is more, and under different flight state overloading load it is big
Small and direction is all different, and overload direction is changeable, and the load of slow test applies more difficulty, and the change of different overload conditions can
It can cause the complete change that experiment is installed, frock cost is larger.Airborne equipment and loading equipemtn installation unit often all compare
Intensive arrangement, space directly apply overloading load more all than narrow to the position of centre of gravity of equipment and equipment installation unit
It is difficult；In addition, existing overloading load be usually quite it is small, can be limited be subject to space and can not to some points directly apply overload carry
Lotus, and when load working condition changes, a large amount of changes need to be carried out to experimental rig to be applied again, waste of time and resources.
